Answer 1

This is how its organized
Eukaryotic
Prokaryotic
Bacteria
Multicellular
Unicellular
Tissue
Organ
Organ system
Digestive system
Respiratory system
Endocrine system
Immune system
Skeletal system
Nervous system
Integumentary system
Muscular system
Circulatory system
Organism
Fungus
Paramecium

Answer 2

tissues make up organs and organs make up organ systems. its that simple.

there is a hierarchy among living organisms that is such:

cell-> tissue-> organs-> organ systems-> organisms

where cells make up tissues to perform a fucntion and tissues make up organs to perform a function and organs make up organisms to perform on emain function : homeostasis.

this is why organs have specific functions- it depends on the tissue type in the organ which depends on the celltype that makes up the tissue

Answer 3

The body is classified into

Cell (e.g Red blood cells, hepatocytes etc) - tissue (epithelial etc) - organ (heart, liver etc) - system (circulatory etc) - organism (human etc)

So, Cardiac muscle is a cell. It is surrounded by an endothelium which together would be heart tissue. Along with other cells it would form the heart. This would form part of the circulatory system which makes part of an organism

Answer 4

Remember, amino acids are the building blocks of cells. Cells are the building blocks for tissues; cells specialize into specific types of tissues. Tissues built of specialized cells form organs. Single or multiple organs make organ systems. All of the organ systems make up the organism, the human body in this case.

Cells are the smallest but most powerful unit in the body. Nutrients and oxygen pass through the cell membrane, producing energy and body heat. Cells have machinery to fight infection. Cells also reproduce to repair injuries or diseases, if they can.

Cells specialize into groups of tissues. Specialized tissues have usually one function.

Tissues are grouped by function into body organs. Organs are entirely specialized for a certain function.

Organs are grouped into organ systems. Each organ system has a separate function.

Organ Systems make up the body, or the organism. We can lose function in some very specific organs or lose an organ altogether in some systems, without it completely impeding the Organism. However, each disruption or dysfunction in an organ can affect the organ system and the organism.

The Organism needs the Organ Systems to function, or the organism can die.

Answer 5

Tissues- group of cells that perform a specific function(ex. muscle tissue)

Organs- a group of tissues(ex. stomach)

Organ system- a group of organs(ex. digestive system)

Answer 6

an organ is many tissues. a tissue is many cells. in others words an organ is many many many cells

Answer 7

Tissue is a group of cells which have a special job to do whilst an organ is formed by a group of tissues with a special job. When you have a group of organs, you have an organ system.

Answer 8

cells.
